...Too bad you can't pull doubles. I'd need triples anyway.
Although Gina isn't serious (the pet trailer from Straight Line Designs is a doghouse, not a functioning trailer) there are teardrop trailers intended to carry dogs, typically behind motorcycles. And recreational double trailers are
legal in some jurisdictions... here in Alberta a pet trailer could tag behind a Scamp
19' (or other fifth-wheel) - sorry, wouldn't work with the Element as tug.
We saw this "camper" somewhere else, and thought it was great. Too small for our ball of fur, though (and $2500 would be better spent on the Boler!)
